You are the product of billions of years of evolutionary change! Approximately 10 million years ago, our ancient ancestors split from the ancestors of modern chimpanzees. This led to the evolution of many different species in the hominin lineage. Ultimately, one species was left standing: ours! Join anthropologist Lindsay Barone to explore the hominins one-by-one in a DNALC Live series called Species Shorts.
In Episode 4, you will:
• Meet the famous Lucy fossil
• Learn about early examples of tool use among the hominins
Presenter: Lindsay Barone
Audience: General Audience

Lomekwian tools were for processing tough tubers?
This video is genuinely good and has a lot of accurate information and I feel she explains this in a way that would allow those who haven’t studied the history of hominin/hominid evolution to understand some concepts that are important in paleoanthropology and she does it in a way that isn’t condescending. Thank you for this video it is very good
that was a lovely talk! very informative, thank you for this video!
Спасибо большое, так интересно.
Thank you for this series!
The most famous one is Lucy that Donald Johanson found and if I remember correctly the find was in Ethiopia. I read his book about finding it when I checked it out from my school library in 6th grade (the whole school K-12 shared a library)
Great content, as usual!
What was the name of the site associated with stone tools mentioned in the video?
Thank you for sreading this valuable knowledge to the population in a clear but not overly simplistic way.
Thanks for sharing
thank u so much !
Thank you
Thank you this helps a lot on my school project 🖤
Is there new archaeological finds showing that older species than Homo habils made tools? Is there anyway to access that information from the actual paleoanthropologist who have studied them? I would be very interested in reading it… I am assuming it’s probably not accessible unless you pay like $50-100 something to read the article but sometimes you can access the Abstract for research articles/writings for free… is it possible to do that? If you could let me know if that is possible I would appreciate that
Cool thanks mate
How many austrolopeticus Fossils have been discovered
Great and factual post 👍. Evolution is 1000000% true. Lucy and ardi are proof.
In the 'forward' of the 100th anniversary edition of Darwin's book, Origin of Species, 1959: "Evolution is unproved and unprovable. We believe it only because the only alternative is special creation, and that is unthinkable.” -Sir Arthur Keith, honest evolutionist!
Do they know what they were using for cutting? Would it have been a large animals tooth given that you think they were not making sophisticated tools?
Stone flakes most likely. Some flakes are sharp as they knock the shavings off of rocks. They probably weren't intentionally sharpening the flakes though.
Great channel. One question: So the foot of Lucy was not completely adapted for bipedalism?
The morphology/anatomy gives a good indication that this species lead a semi-arboreal lifestyle but was definitely a move towards bipedalism in
our evolution
For her species she was actually probably an elder- she was around 30 or 40 but when I read that book I was 12 and I’m 36 now so I may not be remembering the information about what the fossil of the Australopithecus Lucy let scientist learn about her
Cranial capacity of Australopithecus afarnis (in paleoanthropological writings often is abbreviated cc- but is the measure of the skill of the fossils in cubic centimeters) is around 428-600 cubic centimeters… to give an idea about how much smaller that is than our species, Homo sapien, Homo sapien has a cc of 1350 cc)
@@leislschutte6421 Why did chimps from back then have such huge zygomatic arches?
So, my favorite pre-Homo Earthling left stone tool use evidence. Makes sense, since bipedalism frees the hands for multitude of functions.
Donald Johanson was curator of physical anthropology at the Cleveland Museum of Natural History when this discovery was made. I would say the best display (with history) of this discovery in the world is currently on display at the Cleveland, Ohio museum. If you like this subject and get anywhere near the museum, make a visit.
Thanks! I will!
The Gary Larson caveman spelling bee Far Side cartoon brought me here! If you are here because of that too, make sure you watch it through to the end, there are some cool revelations about these Australopithecus guys. ⭐⭐⭐⭐⭐
Talk about a cool ass fun fact about how Lucy got her name.
Very informative. A minor point - sweet potatoes come from the Neotropics.
Yams come from Africa. In The USA, yams can be known as Sweet Potatoes.
Sweet potatoes are a new world plant. Lucy may have eaten tiger nuts. You can get them from Amazon if you want to try what they taste like. Not bad but a lot of fiber unless you get the ones that have been skinned. The fiber is good for you so...
Yams are native to Africa, they're essentially the same thing as sweet potatoes, just a different name. :)
@@haleyrobinson6517 They may or may not taste similar. I don't know. The part eaten grows underground but they are very different plants.
Thank you :). So, it sounds like we have been making bread, or flour for 3 million years. Very faschinating. We started to make our own fruit.
So the footprints, weren’t the like about a size 9 shoe? Also, aren’t they more like a human’s footprint than an ape or chimp like creature? If you have a shoe size of a size 9, wouldn’t that be more like a 5’9” sized individual than a chimp like Lucy? The ardipithecus ramidus has a divergent big toe like a human hand. Therefore, it would be impossible that the footprints were ardipithecus ramidus footprints. In addition, aren’t there issues in correctly dating ash from volcanos? Mt Saint Helen’s proved that to be the case that the ash was found to be hundreds of thousands to millions of years old. Could the answer of the footprints simply be a footprint of a human from a much younger timeline than 3-4 millions ago years ago?
Listening to all this I get tired of fossils...I wish we could advance technology enough to create time travel and see them in the flesh!
Hello, if we evolved from apes, why did the present chimpanzees, gorillas, etc., fall behind?
Firstly, thank you for asking this in a polite tone, rather than screaming in our faces that we're wrong and will rot in hell for blasphemy.
Now, to answer your question, we didn't evolve from modern apes like chimpanzees and gorillas, rather, they are our cousins. We share a common ancestor with them. Of course, it's good to remember that humans are actually classified as apes. Therefore, its logical that the species we know we evolved from (like Australopithecus) were apes as well. A lot further back in time, you'll find the common ancestor of humans and chimpanzees (chimpanzees are actually closer to humans genetically than gorillas). Keep going back and you find the common ancestors of many species we see in the world around us. We share common ancestors with all species meaning all life is related, as we know from the fossil record.
because they branch out. Evolution does not have a "goal". The chimps evolved to fulfill their arboreal niche better.
And to explain branching out properly. If your great grandarents had children: 2 brothers, you may be more acquainted to the family of one brother, your grandpa that started a salt business at the coast. The other brother went on to the mountains to set up a mine and making it the family business.
So now you have 2 branches in the family that went in separate directions.
We have salt makers in one branch and miners on the other.
Same way we get humans on the ground and apes on the trees. They separated long ago. And feel free to add more siblings not jusy the 2 brothers. And of course some of their children make more children that branch out to other businesses.
So you have that constantly branching out tree going down the line.
@@carlosandleon Thanks, I think you’ve probably explained branching evolution better than I have.
@@koba763 Oh I haven't read your comment myself, I just wanted to give my own 2 cents
@@koba763 But thanks a lot :)
Show me upstairs.
Wait - the brown spots are the only actual evidence. The black is all estimated structure. But the whole is given as 'fact'.
Kinda like Ewoks.?
Reminded me of Vader actually.
And the next evolution -- - a robot. Lyndsy Barrone
Very sad that the Donald Johannson's of the world are now gone from paleoanthropology. The field has become staid, lab-sequestered, boring, "diversity" over merit. We need to return to swashbuckling dashing and daring white guys who went out in the field and made these great discoveries.
